To all whom it may concern:

Be it known that 1, DAVID B. Knsronrs, a' citizen of the United States, residing at Philadelp 'a, county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Improvement in Sanders,

' of which the following is a specification.

My invention relates to a IIFW and ulseful 1m rovement in a aratus or su 'n said to the tracks oi i'ailwa s in fron ti b iuh driving wheels, and especially those of electric cars, and has for its ob ect to provide anexceedin 1y simple and effective device of this description which will at all times be under the control of the motorman or driver,

and so arranged that the sand can be agitated to prevent clogging, and so regulated as to constantly feed a given amount of sand to the tracks intermittently or as occasion requires; a further object of my invention is to locate the sand box or reservoir inside of the car beneath the sides thereof, so as to beout of the way and et receive the benefit of the heat of the car In cold weather, so as to keep the sand dry and prevent it from 4 packing, and a still further object of my inscribed in detail, referring to the accomr y drawings forming apart of this specification, 1n winche 1 is a section of a portion of a car showing my improved apparatus applied thereto..; Fi 2, a cross section of the sand box illustrating the mechanism for agitating and feeding the'sandr Fi 3, a section at Figur right angles to Fig. 2, and ig. 4, a plan view my improved ap aratus, the cover being removed so as to s ow the agitator in the sand reservoir.

In ca out my invention as here illusl'trated I provide a reservoir A which may be jofany suitable shape or size to suit the requirements of the use to which it is to be in the reservoir on account of damp ut, and this reservoir is supported upon the rame B, which latter is provided with a funnel shaped receptacle C to which the reservoir is hinged as indicated at D, the object of which is to permit the reservoir to be swung side-wise so as to uncover the receptacle C and gain access to the mechanism depending from the reservoir and contained in the rece tacle, and a suitable fastener D is provide for locking the reservoir in its normally closed position.

The reservoir is provided with a bottom or partition E, which is inclined from the center as clearly shown in Figs. 1 and 2, and the longitudinal sides of this bottom are cut away so as to provide the spaces or outlets F.

I provide the slides G, locating one beneath each of the outlets F and these slides are supported u on the cross rods H so that when these sli es are moved outward to their full extent as shown in Fig. 2 no sand can pass from the reservoir to the receptacle but to the extent that these slides are move inward so will be' the extent of the opening from which the sand may ilow, and for convenience in moving these slides, the handles I attached to each end of each slide project through slides J in the sides of the reservoir in easy reach of the operator.

It sometimes happens that the sand stored weather or other causes becomes packed an does not readil feed through the outlets F, and it there ore is necessary to provide means for agitating the sand when so packed, and this I accomplish by the swinging frame K, which is supported upon the links L, pivoted upon the cross rods M, and an operating rod N is connected to the frame at O and projects through the sides of the reservoir, terminating in a knob or hand hold P, b which the frame may be oscillated, thus reaking up the packing of the same; a further advanta e of this frame is that being located near t e bottom of the reservoir it has a tendency, even when not being oscillated, to prevent the packing of the same.

As the sand is fed from thereservoir to the receptacle 0 at a constant rate it follows that when it is not fed from the receptacle to the tracks at a constantrate the receptacle will become filled and the sand therein is also likely to pack, and to avoid the stopping of the apparatus on account of its packing I provide an agitator (gland hinge the same beneath the bottom of the reservoir, attaching thereto a rod R which projects through the side of the receptacle and terminates in a knob by which the agitator may be oscillated for breaking up the packing of the same.

he bottom of the receiver is open and has secured thereto a flexible receiver S which may be made of any suitable material, and the sides of these chutes converge toward each other asthey extend downward until coming in contact so as to close the chute against the outflow of the end ofthe receiver is held closed by the swinging. rod T pressing upon one side of the receiver and the stationary rods U bearing upon the opposite side of the receiver as clearly shown in Fig. 2, and in order that the sand may be stirred at every movement of the rod T the prongs V project upward from said rod passing through the flexible receiver.

- In locating the sand box within the car beneath one of the sides thereof as shown in Fig. 1, I connect the rod W with the swinging rod T and lead said rod forward connecting it with the bell crank lever X, and provide a foot pin Y by which this bell crank lever ma be depressed to swing the rod T rearwarr, thereby opening the bottom of the flexible receiver to permit the outflow of the sand; a prong Z being attached to the bell crank lever to normally draw it upward and close the receiver. This will put the opening and closing of the chute under the control of the motorman or driver and enable him at any time, by pressing the foot pin to throw a given amount of sand upon the track and by holding the in down the sand will continue to flow, or ii raising and lowering the foot the sand will e fed to the track intermittently.

0. represents a spout which is made in sections-so as to telescope one within the other, and this spout is located immediately beneath the lower end of the receiver so as to convey the sandflowingtherefrom to the tracks in front of the wheels, and a suitable lever b is connected with the lower section of the receiver and runs within easy reach of the motorman so that by operating this lever the lower section of the receiver will be raised until coming in contact with the second section when both of these sections will be raised, thus drawing the lower end of the receiver to an elevated position, thus avoiding it coming in contact with slush or being submerged in water through which the wheels of the car may pass; the teleseo )ing of the sectionsof the spout will always Keep them clear of slush or ice. This is a very important feature of my invention as it overcomes the diflieulties which have heretofore been experienced in connection with feeding sand to the tracks of trolley cars and the like.

Of course I do not wish tobe limited to slacing the sand erneath the sides thereof, as under some sand, and the lower box inside of the car and unconditions it might be more preferable to place this box on the platform of the car and lead the sand b pipes to the proper position on the tracks re ative to the motor wheels.

Having thus fully described my invention, what I claim as new and useful, is--- 1. In combination with a car of the character described, a sand box located within the car, a flexible chute leading from said sand box, means for controlling the outflow of sand through the receiver and means for conveying the sand from the receiver to the tracks, for the purpose set forth.

2. In combination with a car of the character described, a sand box located within the car, a flexible receiver leading from said box, means under control of the motorman for controllin the outflow of sand from the receiver, a te escopic spout leading from the receiver to near the tracks, and means under control of the motorman for raising and lowering said spout, for the purpose set forth.

3. An apparatus for feeding sand to railway tracks consisting of a reservoir, an agitator located within said reservoir, an inclined bottom having outlets at the sides thereof, slides for regulating the flow of sand through said outlets, a funnel shaped receptacle, an agitator located within said receptacle, means for oscillating said agitator, a flexible receiver leading from the rece tacle and means for controlling the outflow o sand from the chute for the purpose set forth.

4. In a sanding apparatus, the combination of a reservoir, an agitator consisting of a swinging frame located in said reservoir, an inclined bottom for the reservoir havin outlets formed upon the sides thereof, slides located beneath the outlets, means for adjusting the slides from the outside of the reservoir, a receptacle to which the reservoir is hinged, an agitator pivoted on the one side of the bottom and projecting downward into the receptacle, means for actuating the last named agitator from the outside of the receptacle, a flexible receiver secured to the bottom of the receptacle, a swinging rod adapted to open and close the bottom of the receiver, prongs projecting upward from said swingin rod into the receiver, a spout composed of sections adapted to telescope located eneath the receiver, and means under control of the motorman for regulating the flow of sand from the receiver and for raising and lowering the sections of the spout, substantially as and for the pur ose set forth.
